[英]How to Mock NamespaceManager Class Methods Using Moq?
https://docs.microsoft.com/en-us/dotnet/api/microsoft.servicebus.namespacemanager?redirectedfrom=MSDN#microsoft_servicebus_namespacemanager https://docs.microsoft.com/zh-cn/dotnet/api/microsoft.servicebus.namespacemanager?redirectedfrom=MSDN#microsoft_servicebus_namespacemanager
I want to mock CreateTopicAsync method. 我想模拟CreateTopicAsync方法。 But because of the sealed nature of the class i am not able to mock the class.
但是由于班级的封闭性,我无法模拟班级。 Any one Knows?
有谁知道?
You can't mock a sealed
class. 您不能嘲笑
sealed
类。 Mocking relies on inheritence to build on the fly copies of the data. 模拟依赖于继承来构建数据的实时副本。 So trying to mock a
sealed
class is impossible. 因此,尝试模拟
sealed
类是不可能的。
What you can do is write a wrapper: 您可以做的是编写一个包装器:
public class NamespaceManagerWrapper : INamespaceManagerWrapper
{
private NamespaceManager _instance;
public NamespaceManagerWrapper(NamespaceManager instance)
{
_instance = instance;
}
public ConsumerGroupDescription CreateConsumerGroup(ConsumerGroupDescription description)
{
return _instace.CreateConsumerGroup(description);
}
etc....
}
interface for the mock 模拟界面
public interface INamespaceManagerWrapper
{
ConsumerGroupDescription CreateConsumerGroup(ConsumerGroupDescription description);
....etc.
}
your method should now accept your wrapper interface on the original object: 您的方法现在应该在原始对象上接受包装器接口:
public void myMethod(INamespaceManagerWrapper mockableObj)
{
...
mockableObj.CreateConsumerGroup(description);
...
}
Now you can mock the interface: 现在您可以模拟界面:
Mock<INamespaceManagerWrapper> namespaceManager = new Mock<INamespaceManagerWrapper>();
....etc.
myObj.myMethod(namespaceManager.Object);
Unfortunatly that's the best you can do. 不幸的是,这是您可以做的最好的事情。 It's a siliar implementation to HttpContextWrapper
这是HttpContextWrapper的辅助实现
